HVAC Contractor in Mendon, MA
Oil and propane heat is our daily work in Mendon — burner service, repairs, tank replacements, plus central air and zoning for the bigger houses.
Hannon Heating & Air Conditioning is an HVAC contractor serving Mendon, MA from Bellingham, 12 to 18 minutes west on Hartford Avenue. Most of Mendon sits beyond the gas mains, so oil and propane heat is our daily work here: burner service, boiler and furnace repair, tank replacement, plus central air and zoning for the larger newer homes.
West on Hartford Avenue to Rt 16
Hartford Avenue runs from Bellingham straight through to Mendon, meeting Rt 16 near the Main Street town center. That's a 12-to-18-minute drive for our trucks, short enough to fold a Mendon call into most days' routes. We cover the whole town: the roads around Lake Nipmuc, the stretch out past Southwick's Zoo (New England's largest), and the neighborhoods toward the Mendon Twin Drive-In, one of only three drive-ins left in Massachusetts. There's no Mendon office; we come from Bellingham, and the person on the phone is the person doing the work.

Oil and Propane Country
Nearly all of Mendon lives beyond the natural gas mains, which makes this oil and propane territory, and that suits us. Paul has serviced oil heat for more than 30 years: annual oil burner cleanings, nozzle and filter changes, combustion tuning, and no-heat calls in January. We repair and replace oil and propane boilers and furnaces alike, and we're Roth certified for double-wall oil tank installations when the old steel tank starts weeping.
Big Houses, Multiple Zones
Mendon's newer stock runs large: acre-plus lots along wooded roads, colonials and contemporaries with square footage that one thermostat can't govern. Zoning systems split the house so bedrooms and living space heat and cool independently, and central air is a natural add for houses this size. If your second floor bakes while the first floor freezes, that's a zoning problem, and it's fixable.
Old Houses in an Old Town
Mendon is the second-oldest town in Worcester County, settled in 1667, and some of its houses have been keeping people warm for a very long time. We're comfortable in antique homes: boiler systems that have outlived several owners, radiators, and the judgment calls about what to preserve and what to replace. When one of those systems finally goes, we quote the replacement before any work starts, and estimates on system replacements are free.
Permits Without the Paperwork
Heating and cooling replacements in Mendon go through the Building Department at Town Hall, 18 Main St, and we handle the permit paperwork ourselves: filing, the inspection, the close-out. You make none of the trips.
